Question

prove
${x}^{2} - {y}^{2} = (x + y)(x - y)\ \textless \ br /\ \textgreater$
​

Answer 1

${\large{\pmb{\pink{Required \: \: Answer}}}}$

To Solve:

Prove x² - y² = (x + y) (x - y)

Solⁿ:

Solve (x + y) (x - y) through Algebraic Multiplication.

$(x +y)(x - y) \\ \\ x(x - y) + y(x - y) \\ \\ {x}^{2} - xy + xy - {y}^{2} \\ \\ { \boxed { \red{{x}^{2} - {y}^{2} }}} \\ \\ hence \: \: proved$
